Label and describe the key points on a stress-strain curve

  1. Modulus of Elasticity: Slope on the linear portion of the curve; concise description of a material’s linear elastic behavior
  2. Yield Strength: Max limit of stress the material can endure so that the material with still stretch elastically
  3. Ultimate Tensile Strength: Point where given material cannot handle any more increases in tensile stress:
  4. Fracture: Maximum strain at which a specimen fractures.
